(Harrisburg) -- Governor Corbett is taking to the road to explain and defend his budget proposals. Sure, 20 and 30 percent cuts to state-supported colleges and universities might sound bad. But the governor says take a look at what those cuts would mean for the schools’ overall operating budgets. He says they would all make up between one and four percent of the schools’ spending. "We have to adjust. In difficult economic times, they have to adjust. And frankly, I don’t accept the fact that they automatically have to raise tuition. You have to make yourself lean," Corbett says. The proposed 20 percent cut to the State System of Higher Education would amount to 3.5 percent of the system’s operating budget. The cut to Penn State would amount to a one-point-six percent decrease in its overall budget. For Pitt, the proposed reduction would make a 2.1 percent drop to the budget. Temple University’s planned cut would be a 1.8 percent reduction to the school’s overall budget.
